Abstract
Description
本発明は主に加齢などによる聴覚障害を矯正することを目的とする補聴器具に関する。 The present invention relates to a hearing aid mainly intended to correct hearing impairment due to aging or the like.
従来、補聴器具としては音声増幅器を備えるものが大半であった。このような従来の補聴器は不要な騒音までも同時に増幅するため、会話において肝心な情報を正確に得ることが困難であるという問題を抱えていた。 Conventionally, most hearing aids have an audio amplifier. Such conventional hearing aids have a problem that it is difficult to accurately obtain important information in conversation because unnecessary noise is simultaneously amplified.
このような状況下、例えば特許文献１に記載されているような電源を必要としないタイプの補聴器具が提案されている。特許文献１には、それぞれ穴が開いている第１の要素と第２の要素からなり、外耳の内外を等圧とする耳栓が開示されている。そして、該耳栓を用いれば騒音や不快な音を遮断した状態で会話ができることが記載されている。 Under such circumstances, for example, a hearing aid of the type that does not require a power source as described in Patent Document 1 has been proposed. Patent Document 1 discloses an earplug that is composed of a first element and a second element each having a hole, and has an equal pressure on the inside and outside of the outer ear. And it is described that if the earplug is used, a conversation can be performed in a state where noise and unpleasant sound are cut off.
上述の通り、従来の補聴器は不要な騒音までも増幅するため、会話が困難になる場合があるという問題を有していた。
一方、特許文献１に記載の耳栓は、使用時に外耳をほとんど塞いでしまうため、騒音以外の音も低減してしまうという問題があった。
As described above, the conventional hearing aid has a problem that conversation may be difficult because it amplifies even unnecessary noise.
On the other hand, the earplug described in Patent Document 1 has a problem in that sound other than noise is reduced because it almost blocks the outer ear during use.
このような問題に鑑み、本発明の解決しようとする課題は、騒音を遮断しつつも、必要な音については明瞭に聴き取ることを可能にする新規の補聴器具を提供することにある。 In view of such a problem, the problem to be solved by the present invention is to provide a novel hearing aid that enables a user to clearly hear a necessary sound while blocking noise.
本発明者らは鋭意研究努力により、特許文献１に記載の耳栓のように外耳を閉塞する構成とせずとも、騒音遮断効果が得られることを見いだした。さらに、このような形態の補聴器具を使用すれば、騒音以外の必要な音を明瞭に聴き取ることができることを見出した。 The inventors of the present invention have made extensive research efforts and found that a noise blocking effect can be obtained without the configuration of closing the outer ear like the earplug described in Patent Document 1. Furthermore, it has been found that if a hearing aid of such a form is used, necessary sounds other than noise can be clearly heard.

以下、本発明の実施例について説明するが、本発明の技術的範囲は実施例に限定されないことは言うまでもない。 Examples of the present invention will be described below, but it goes without saying that the technical scope of the present invention is not limited to the examples.
＜実施例１＞
実施例１について図１〜３を参照しながら説明を加える。
実施例１の補聴器具１０は、筒状の器具本体２０と集音体３０を備える。
器具本体２０は外耳道への挿入端側と、その反対側（反挿入端側）にそれぞれ開口部２１及び開口部２２を備えている。そして、集音体３０は器具本体２０の開口部２２から延長するように一体に設けられている。そのため、器具本体２０の開口部２２は、集音体３０の幅狭な開口部３２と一体となっている（図１及び２）。
<Example 1>
The first embodiment will be described with reference to FIGS.
The hearing aid 10 of the first embodiment includes a tubular instrument body 20 and a sound collector 30.
The instrument body 20 includes an opening 21 and an opening 22 on the insertion end side to the external auditory canal and on the opposite side (opposite insertion end side), respectively. The sound collector 30 is integrally provided so as to extend from the opening 22 of the instrument body 20. Therefore, the opening 22 of the instrument body 20 is integrated with the narrow opening 32 of the sound collector 30 (FIGS. 1 and 2).
本発明においては集音体３０を有さず、器具本体２０のみからなる形態としてもよい。このような実施の形態としても、騒音遮断効果と音の明瞭化効果を発揮する。
好ましくは実施例１のように集音体３０を設ける。集音体３０を設けることによって集音効果が向上するため、小さな音も明瞭に聴きとることができるようになる。
器具本体２０と集音体３０の材料は同一であっても異なっていても良いが、好ましくは同一材料で一体に構成する。
In this invention, it is good also as a form which does not have the sound collection body 30 but consists only of the instrument main body 20. FIG. Such an embodiment also exhibits a noise blocking effect and a sound clarification effect.
Preferably, the sound collector 30 is provided as in the first embodiment. Since the sound collecting effect is improved by providing the sound collecting body 30, a small sound can be heard clearly.
The material of the instrument main body 20 and the sound collector 30 may be the same or different, but are preferably formed integrally with the same material.
実施例１の補聴器具１０における器具本体２０と集音体３０の材料としては、ポリエチレン、ポリプロピレン、ポリエステル、ポリウレタン等の合成樹脂、シリコーン系高分子、ウレタンゴム等の合成ゴム、天然ゴムなど、可撓性材料が好ましく例示できる。
このような可撓性材料を用いることで、器具本体２０の外耳道４１の内壁への密着性を向上させることができ、より騒音遮断効果と必要な音の明瞭化を向上させることができる。
Examples of the material of the instrument body 20 and the sound collector 30 in the hearing aid 10 of Example 1 include synthetic resins such as polyethylene, polypropylene, polyester, and polyurethane, silicone-based polymers, synthetic rubbers such as urethane rubber, and natural rubber. A flexible material is preferably exemplified.
By using such a flexible material, it is possible to improve the adhesion of the instrument body 20 to the inner wall of the external auditory canal 41, and to further improve the noise blocking effect and necessary sound clarification.
また、本発明のより好ましい形態では、補聴器具１０の素材としてシリコーン系高分子を採用する。
シリコーン系高分子材料は、人工発声装置における疑似気道、疑似声帯、疑似舌、疑似唇の素材として用いられているように、人間の声の周波数と共鳴しやすいという性質を有する。そのため、シリコーン系高分子材料により構成された補聴器具１０は、雑音には共鳴せず、人間の声に共鳴して振動し、直接又は骨振動を介して内耳に音を伝える。つまり、シリコーン系高分子材料により構成された補聴器具１０によれば、騒音環境下で会話する場合に、相手の声が小さかったとしても聴き取ることができる。
In a more preferred embodiment of the present invention, a silicone polymer is used as the material of the hearing aid 10.
Silicone polymer materials have the property of being easily resonated with the frequency of human voices, as used as materials for pseudo airways, pseudo vocal cords, pseudo tongues, and pseudo lips in artificial speech devices. Therefore, the hearing aid 10 made of a silicone polymer material does not resonate with noise, vibrates in resonance with a human voice, and transmits sound to the inner ear directly or via bone vibration. That is, according to the hearing aid device 10 made of a silicone-based polymer material, when talking in a noisy environment, it can be heard even if the other party's voice is low.
器具本体２０の形状は、外耳道４１へ挿入した際に外耳道４１の内壁に略密着する形状であればよく（図３）、外耳道４１への挿入前に当該形状である必要は無い（図１及び２）。 The shape of the instrument main body 20 may be a shape that is substantially in close contact with the inner wall of the ear canal 41 when inserted into the ear canal 41 (FIG. 3), and does not need to be the shape before insertion into the ear canal 41 (FIG. 1 and FIG. 2).
補聴器具１０において、開口部２１と開口部２２は実質的に狭窄することなく連通している。ここで、「実質的に狭窄している」との文言には、外耳道の形状に起因して開口部２１及び開口部２２、並びに器具本体２０の内部空間が狭窄することは含まない。 In the hearing aid 10, the opening 21 and the opening 22 communicate with each other without being substantially narrowed. Here, the phrase “substantially constricted” does not include the constriction of the opening 21 and the opening 22 and the internal space of the instrument body 20 due to the shape of the ear canal.
器具本体２０の長さは、器具本体２０を反挿入端側の端部が耳垢腺４２の近傍に位置するまで挿入したとき、挿入端側の端部が骨部外耳道４１２の近傍まで達する長さとすることが好ましい（図３）。
器具本体をこのような長さとすることによって骨伝導を利用することができ、より小さな音であっても聴き取ることが可能になる。
The length of the instrument body 20 is such that when the instrument body 20 is inserted until the end on the anti-insertion end side is located in the vicinity of the ear wax gland 42, the end on the insertion end side reaches the vicinity of the bone external auditory canal 412. It is preferable to do this (FIG. 3).
By making the instrument body such a length, bone conduction can be used, and even a smaller sound can be heard.
集音体３０の大きさは特に限定されないが、軟骨部外耳道４１１の入り口近傍に幅広の開口部３１が位置する大きさとすることが好ましい（図３）。
また、集音体３０の外周が軟骨部外耳道４１１の内壁に接するような形状とすることが好ましい（図３）。
集音体３０をこのような形状とすることにより、集音体３０の集音効果を向上することができる。
The size of the sound collector 30 is not particularly limited, but it is preferable that the wide opening 31 be positioned near the entrance of the cartilage outer ear canal 411 (FIG. 3).
Further, it is preferable that the outer periphery of the sound collector 30 is in contact with the inner wall of the cartilage outer ear canal 411 (FIG. 3).
By making the sound collector 30 into such a shape, the sound collection effect of the sound collector 30 can be improved.
器具本体２０及び集音体３０の厚みは、特に限定されないが、１〜２ｍｍであることが好ましい。このような厚みとすることによって、器具本体２０の内部空間の径を十分に確保することができ、使用者に閉塞感や圧迫感を感じさせない。 The thicknesses of the instrument body 20 and the sound collector 30 are not particularly limited, but are preferably 1 to 2 mm. By setting it as such thickness, the diameter of the internal space of the instrument main body 20 can be sufficiently ensured, and the user does not feel a sense of blockage or pressure.
本発明は加齢による難聴障害の矯正のための補聴器具に応用することができる。 The present invention can be applied to hearing aids for correcting deafness disorders due to aging.
